Application filed October 21, 1922. Serial No. 595,996.

M invention relates to an improvement in tinning mechanisms, and more particularly to provide such a mechanism wherein tubing or the like that is to be tinned may that 1s, the process shall be substantially-endless wherein a tubing of any desired length may be run through the tinning mechanism as it comes from the forming machine and wherein ,the advancing portion of the tubing is first coated and cleaned with acid, then passed into the tinning bath and next passed through a cooling medium, all of the successive o rations going on simultaneously u on the adjacent portions of the constantly a vancing tubing. I

The invention has among its other objects the production of a device of the kind de-- scribed which is simple, convenient, compact, durable, reliable, eflicient and satisfoun'd applicable. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from novel construction, 'bination of parts characters indicate the disclosures herein given.

To this end my invention consists in the arrangement and comherei'n shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference like or corresponding parts,

Fig. 1 is a front elevation of my device;

Fig. 2 is a section taken on the line 2-2 of Fig. 3;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig.4 is bath; 7

Fig. 5 is a section taken on the line 55 of Fig. 4;

Fig. 6 is a section taken on the line 66 of Fig. 4; 1 g

. Fig. 7 is a section taken on the line 77 of Fig. 4;

Fig. 8 is a section taken on the line 8-8 of Fig. 4;

Fig. 9 is a section through the cooling bath;

Fig. 10 is a section taken on the line 1010 of Fig. 9;

Fig. 11 is a section taken on the line 11-11 of Fig. 9.

In the drawings, trated the preferred a section through the tinning wherein I have illusembodiment of my invention, there is shown means for successively applying acid, tinning and cooling a constantly advancing continuous length of tubing 1, saidv means being indicated at 2, 3 and 4 respectively.

The acid-applying means 2 is made up preferably of a pair of absorbent members, 5-5, (see Figs. 2 and 3) preferably movable relative to each other as shown to and from each other and provided with an opening 6 therethrough, engageable with the tubing and through which the tubing must pass. The members 5-5 are controlled in their movement to and from one another by any suitable means, as for instance the gear means 7-7, having links 8-8 connected to said members 5-5. The links 8-8 shown in Figs. 2 and 3 are fixed to the shafts upon which they are mounted, and said shafts are supported in bearings, .as shown. Each shaft carries a gear wheel 7, the two gear wheels intermeshing so as to operate together and causethe said shafts and links to also operate simultaneously. A lever A is secured to one of the gear wheels 7, as illustrated, in any preferred manner, by means of which the gears are slightly rotated.

Each pair of links carries one member of the box which contains the absorbing material 5 through the center 6 of which the pipe to be tinned is guided. It will thus be seen by referring to Fig. 3 that a movement of the lever A to the left, as indicated by dotted lines, will cause the links and their connected parts to separate, opening up the passage 6 so that the pipe may be readily placed therein. When the pipe has ben suitably positioned, manipulating the lever 8 and moving it tothe right will cause the pairs of links with their associated parts to approach each other, closing the absorbent material snugly down upon the pipe. A container or reservoir 9 is carried above one of the members 5, and has openings 10 therethrough in communication with the material of the absorbent members to saturate them, so that when the tubing is passed therethrough it will be frictionally and slid ably engaged'by the absorbent members, and be cleaned with the acid.

The tinning bath 3 is arranged adjacent '13, respectively, substantially at the normal level 14 of the soldering or lirfiuid in the 1y inserted provide a pipe 16 may be described in detail.

- the tubing passe tubing.

Leading into and out of the tank 11 are tubular guides 17 and 18 res ectively, said guides having their outer en s at a higher elevation than the normal level 14 of the liquid in the tank, and are inclined downwardly so as to be below said level of liquid at their inper lelnds,l sailidl inner eiids of the ides re era si t y space apart, as li own f1 Fi 4. O lenin 19 may be and are preferab y provlded t rough the walls of the guides 17 and 18. at spaced intervals, so that the contents of the tank may come in direct contact with the tubing passed through the guides. The guides are. substantially of a lar or internal diameter than t? therethrough, exce t at spaced intervals wherein are arranged ushing 20 having a bore substantially equal to the size of the tubing so as to center or guide and prevent the bending, crushing or distortion of the tubing, and also to serve for the purpose of partially restricting the flow of the tinnin material longitudinally with the tubing. Ihe end guide 18 may be provided with a renewable tip 18" if so desired. Thus it is seen that none of the tinning material will he s illed from the tank, nor carried out of t e tank by the The tubing as it comes from the hot tinning bath is very hot and must be cooled before it can be handled. The cooling means 4 is arranged adi'lacent the discharge side of the tinnin bat' and comprises a tube or sleeve 20, 9) having openings 21 through its wall. A jacket 22 encircles the sleeve 20 and is radially s aced therefrom to provide an annular cham er therebetween said chamber having an inlet for the water connection 23.

The inlet end of the tube 20 is flared, as at 24, while the remainder of said tube is of a diameter a littlelarger than the diameter of the tubing handled so that the cool-' ing water may enter tlirough the opening 21 and spray the tube. A tank 25 is prefer ably arranged beneath the water-applying parts so as to provide a drain therefor.

As shown in Fig. 1, all of said parts may be situated at a convenient elevation for practical handling, by means of the suitable supports or tables 26. The tube when of the lock seam type if effectively sealed or sol- -ing means comprising parallel deredby the bath, and is coated or turned, as it 1s termed, so that it may be very eflic ently used n making up radiators: or the like for automobiles, or for other uses.

From .the'foregoing description it will be seen that ,there is provided means plying the acid, tin and cooling lengtof tubin without stopping or inter rusting the a vancing movement of .the tlhlllg as it comes from the formin machine and without any of the aci tin, or water reachin the interior ofthe tubing. Consequent y, the tubing may be efiiciently cost.
